Elbow adhesions are determined by the degree of adhesion based on elbow flexion and extension activities and anterior and posterior rotation. It can also be determined by MRI. Elbow joint adhesion is caused by prolonged braking time after surgery for fractures around the elbow joint or traumatic arthritis. Normal elbow flexion and extension angle is 135~150 degrees, anterior and posterior rotation is 80~90 degrees, and elbow hyperextension is 10~15 degrees. When the adhesion occurs, the elbow joint activity is obviously limited, and the angle becomes smaller to consider that the adhesion is more serious. The degree of adhesion of soft tissues, muscles and ligaments around the elbow joint can be detected by MRI. When the elbow joint mobility is limited, go to the hospital specialist for treatment.
